Specification of Letters Patent.

Application filed October 28, 1916. Serial No. 127,056.

To all whom it may ccmcem:

Be it known that I, Fnnn S. CARR, a citizen of the United States, residing at Brookline in the county of Norfolk and State of Massachusetts, have invented new and useful Improvements in Turn-Button Fasteners, of which the following is a specification.

This invention relates to a fastener for carriage curtains and the like, comprising a shank or stud adapted to be attached to a support such as the body of a vehlcle or a member of the frame of a vehicle top, and formed to enter a buttonhole or eyelet in a curtain or cover portion, and an oblong button pivoted to the shank and formed to register with and freely enter a buttonhole when turned to one position and to be turned crosswise of the buttonhole to overhang portions of the margin thereof and confine the curtain or cover portion against removal from the shank. The shank'is usually of oblong form corresponding to that of the buttonhole and button.

Fasteners of this character, known as turn-button fasteners, are provided with means for yieldingly confining the button either in registration with the shank or crosswise thereof, so that the button will remain in either position until forcibly turned therefrom.

The invention has for its chief object to enable the button to be yieldingly confined in either of the described positions without the employment of retaining devices supplemental to the shank and button and formed separately therefrom, the invention, in its preferred form, being embodied in only two parts or pieces which include the means for yieldingly confining the button in its different positions.

Another object of the invention is to provide a turn-button fastener constructed entirely of sheet metal and therefore of minimum weight andcost.

The invention consists in the improvements which I will now proceed to describe and. claim.

Of the accompanying drawings forming a part of this specificat1on,-

Figure 1 represents a side view of a turnbutton fastener embodying my invention;

Fig. 2 represents an end view of the same;

Fig. 14 represents a view similar to Fig. 1, showing amodification; v

Fig. '15 represents a view similar to a portion of Fig. 8, illustrating amodification.

Figs. 16, 17 and 18 are sectional views illustrating a modification.

Fig. 19 represents a view similar to a portion of Fig. 8 showing a. modification.

The same reference characters indicate the same or similar parts in all the views.

In the drawings, 16 represents the shank and 17 the button of a turn-button fastener.

In the embodiment of the invention here from sheet metal by suitable dies, of oblong form in cross section and provided at its inner end with an attaching base 18 adapted to be secured to a support in any suitable way. For example, the base may be provided with integral prongs 19 adapted to penetrate and be clenched upon the part or member that carries the shank. Figs. 4 and 5 show an attaching base which is elongated and provided with orifices 20 adapted to receive attaching screws.

The outer end of the shank is practically closed to provide a flat face, which is provided with frictional button-engaging means to yieldingly confine the button in different positions, said means being embodied in a masses v Figs. 2 and 8, to overhang the longer sides of the shank and portions of the margin of a buttonhole on the shank.

The margin of the button shown by Figs. 2, 3, 9, 10, 11 and 14 is provided with slots 24 preferably formed in the ends of the button, as shown by Figs. 2 and 3, although said slots may be formed in the sides of the button, as shown by Fig. 14. The slots sub-v divide the margin ,of the button into resilient portions or jaws the inwardly facing sides of 'which are adapted to yieldingly engage opposite sides 22, of the polygonal projection, as indicated by Figs. 10 and 11, and thus yieldingly confine the button in either of the two positions described, the yielding or resilient portions of the button being adapted to spring inwardly against the faces 22 and have elongated contact therewith, so that considerable force is reuired to turn the button from either position to the other. j

The button is therefore provided with a resilient inwardly facing expansible margin or marginal portion adapted to frictionally engage fixed outwardly facing sides of the polygonal projection on the shank 16. The elongated contact between said marginal portionand fixed sides prevents liability of accidental rotation of the button.

A pivotal connection is provided between the button and the shank, said connection preferably including a hollow stud 25 which is integral with the button and projects from the crown portion thereof intothe interior of the button. Said stud is provided with a reduced inner end portion 26 and with an annular shoulder 27 between the portion 26 and the body of the stud. The projection 21 is provided with a circular aperture 28 constitutin a bearing in which the stud portion 26 is ournaled, said portion being inserted in the orifice 28 and upset on the under side of the projection 21, as shown by Figs. 8 and 9. The projection 21 therefore constitutes a bearing and a seat for the stud 25, the shoulder 27 being seated on one side of said projection, and the upset portion 26 being seated on the opposite side.

The button may be formed from a blank 17, said blank being flat and provided with the stud 25, as indicated by Flgs. 12 and 13. The blank is provided with curved edges 17 b which form the sides of the slots 24 when the blank is bent by the action of suitable dies to form the hollow cupped button. v

It will now be seen that the described fastenermay be made of only two pieces or parts, and that said parts'have provision for suitably connecting the button" and shank and for yieldingly confining the button in different positions relatively to the shank.

I do not limit myself to a pivot stud integral with the button. As shown by Fig. 15, a tubular stud25 may be employed, said stud having a head 25 seated on the margin of an orifice in the crown of the button, the

' inner end of the stud being inserted in the aperture of the rojection 21 and upset on the under side of said projection.

The slots 24 may be omitted, the margin of the cupped button being continuous as shown by Figs. 16, 17 and 18. In this case, the-flexibility of the button margin enables it to closely hug the projection 21 when the button is in either of the positions shown by Figs. 16 and 18, and to bulge outwardly ghenlizn the intermediate position shown by s shown by Fig. 19, a tubular stud 25 may be formed integral with the projection 21 on the shank 16, the outer end of the-stud being extended through an orifice formed in the crown of the button 17 and upset to secure the button to the stud.

The polygonal projection 21 having outwardly facing sides, is adapted to cotiperate as described, with a cupped button, the external surface of which is flush with the external surface of the shank when the button registers with the stud to permit the application of a curtain eyelet, so that the eyelet may be easily moved to place on the shank.

As implied in the foregoing description and in the following claims, I am' not limited to the specific construction of the preferred embodiment of my improvement shown by the drawing, except as otherwise required in certain of the more limited claims. I
